| _florent_ | mithro: thanks, good idea, i'll add this (that's already in Linux-on-LiteX-VexRiscv README but could emphasize things here yes) | 07:51 |
|---|---|---|
| _florent_ | loxodes: i could have a closer look tomorrow if you want | 07:56 |
| loxodes | _florent_: thanks for the offer, first let me see if I can come up with a minimal project that replicates the issue | 08:26 |
| loxodes | I see there is now a wishbone dma writer core, I'll try that | 08:36 |

| loxodes | _florent_: If you think this is worth investigating, I've replicated the problem on a fresh project which uses the wishbone dma writer core here: https://github.com/loxodes/dma_burst | 20:52 |
| tpb | Title: GitHub - loxodes/dma_burst: Project to illustrate issue with writing to memory on LiteX (at github.com) | 20:52 |

| zyp | loxodes, that looks like a fun issue to debug | 21:22 |
| zyp | loxodes, there seems to be a pattern to it, notice how it only succeeds for 0b000xxx, 0b001xxx, 0b011xxx and 0b111xxx | 21:27 |
| zyp | I bet if you extend it from 64 to 256, it'll also fail for 64-119 and 128-247 | 21:28 |
| mithro | _florent_: I would like to figure out a way that you can "automagically" also use any FuseSoC module in LiteX | 22:30 |
| loxodes | zyp: good point, I'll try and dig into patterns on where it fails. extened to 256, it tends to fail on either 16-23, 32-55, 96-255 or 16-31, 40-55, 96-255 | 22:45 |
